Note:
There are 3 alternate title slides.
The first is simple.
The second is a little goofy (changing when you click Enter).
The third is like the second, but with a conventional double T in the word ‘setting’.
Please delete two of the three, keeping only your preference, then delete this slide.

I. Weather and weather differences affect where and how humans can live.
A. The rotation of the earth, different amounts of solar heat absorption at different latitudes, and different rates of heat absorption of land and water cause weather.

D. The earth has periodically grown warmer and colder, with the polar regions being covered with ice and then uncovered.
1. The world’s oceans have risen and fallen with the change in the size of the polar ice caps.
2. Because most of the world’s land lies in the northern half of the world, the growth and decline of the southern polar ice cap have had little effect on human history, except on ocean levels.
3. We are in a period that is between a warm and a cold age.

I. Weather and weather differences affect where and how humans can live.
E. The last time a big climate change occurred, an ice age resulted, not a warm age.
1. The average temperature of the earth was 9 - colder than today.
2. Temperate climate belts moved southward, with tropical climates
disappearing altogether.3. Humans, by and large, followed the climate
belts southward.

II. The hot core of the earth has had many effects on the earth.
A. It led to the creation of much of earth’s topography.
1. Plate movement created mountain ranges.
2. Molten magma erupting through the crust created single mountains.
B. It features a magnetic field that makes compasses possible.
C. It protects our atmosphere by diverting solar radiation that would otherwise strip the earth of its atmosphere.T

III. The world is divided into three habitable landmasses.
A. Afro-Eurasia is the largest, and apparently where humans originated.
B. America is the middle-sized continent.C. Australia is the smallest.

IV. The vast amounts of water in lakes, rivers, and oceans, have influenced human development.
A. Lakes, rivers, and oceans created first barriers to travel, then paths.
1. Until the development of paved roads, water travel was always easier than land travel.

V. Topography has affected human development.
A. Mountains acted as barriers to trade, travel, and, often, cultures.
1. Mountain ranges provided natural boundaries between groups of people.B. Valleys have provided natural routes for water.
1. Being flat, valleys provide good farmland and roads.
2. Where necessary, rivers can provide irrigation, either directly, or with canals fed by the river.

VI. The distribution of natural resources has affected human development, especially in civilizations.
A. Different cultures have used or ignored various resources.B. Countries with many resources–and who have used them–have had advantages over countries with fewer resources.

VII. The varied availability of food–in both animal and plant form–has enabled human survival.
A. Coastal cultures have often looked to the sea for food.B. Some cultures have limited their food to a narrow range of options while others have eaten just about anything available.

B. Interaction between two areas over a long period of time has enabled each group to become accustomed to the other’s diseases, transforming severe diseases into less dangerous childhood ones.

E. Wherever lakes and oceans bordered human settlements, boats have aided travel.
1. Boats with sails and rowers can move in any direction, no matter what the wind is doing (but rowing take more work).

B. Ways of life reflect the environment, although wealth and advanced technology can overcome this.
1. Food and clothing reflect the environment.2. Shelter and occupations reflect the environment.
a. American housing since World War II often ignores the environment, using heating and air conditioning to do so.
3. Even language and ideas reflect the environment.
